Public Insurance Expansions and the Health of Immigrant and Native ChildreBy Erin Todd Bronchett

Extending the INS data in Watson (forthcoming) through 2009 is not possible because of a sub-
stantial change in recording of enforcement in 2003. Instead, I construct the enforcement variable
for 1998-2009 using data from the Transactional Records Access Clearinghouse (TRAC) Immi-
gration Reports. I calculate the number of deportations per 1,000 foreign-born in each of the 25 INS clusters from 1998 through 2009. I also computed the number of immigration court cases
per 1,000 foreign-born, but that variable had less predictive power. I use the American National
Election Study (ANES) to capture state-year variation in negative attitudes towards immigration.....[Citing TRAC research].
